from django import forms

class a(forms.Form):
    name = forms.CharField(initial='Your name')
    url = forms.URLField(initial='Your Web site')
    comment = forms.CharField()
data = {'name': 'hahaha', 'url': '', 'comment': 'Foo'}

f = a(data,auto_id=False)

#print f.is_valid()
print f.errors

错误：
